The Auto*Therm 390 is a pulsed and continuous shortwave diathermy with a variety of frequencies and pulse widths to choose from. Choose from 2 different modes of application - deep penetration with inductive coil diathermy, or shallow penetration with capacitive electrodes.

This unit features soft rubber electrodes for the application of shortwave diathermy energy. An easy-to-use membrane panel guides the user through setup. A patient pullcord allows the patient to stop all output if the treatment becomes uncomfortable.

Weighing only 15 pounds, this unit can be easily carried between treatment rooms or to the patient. There is a handle molded into the case to allow the clinician to carry it around the clinic.

Since 1968, Mettler Electronics has produced shortwave diathermy (SWD) units that produce comforting deep heat in muscle tissues. Shortwave diathermy is used when the clinician needs to provide deep heat to a larger area than normally covered by ultrasound.
